Title: Optical testing for genuineness of bank notes and similar paper bills
Inventor: GOTAAS EINAR
IPC: G07D7/00
Filed: 1990-08-17
Abstract: A method and a means for checking genuineness of paper money are based upon detection of the characteristic differences in the printing process for genuine bank notes and counterfeit bills produced with a colour copying machine. The detection is conducted in narrow wavelength bands respectively in typical red and blue colour ranges, and simultaneously in particular directions, with reflected and scattered light. Detection of intensity in a correspondingly narrow band near the maximum sensitivity range of the eye, i.e. in the green range, and in another direction, is also conducted for reference purposes. Preferably the measurement is made in a particularly selected point where the contents of blue and red in the print of the genuine bank note is at an extremum, i.e.  high or low.

Abstract: A B S T R A C T                             PROCESSES           Methods for recombinant production in procayotic microorganisms such as E.coli of ribotoxins such as restrictocin, alpha-sarcin and mitogillin are described.  Known methods were relatively low yielding and not cost effective for commercial use such as in the pharmaceutical industry where relatively large quantities of toxin with consistent batch to batch quality may be required for immunotoxin production.  Use of recombinant methods of production open up the possibility of making ribotoxin analogues.  Toxicity of ribotoxins was recognised as a concern in development of a high yielding cost effective production method.  Methods for high yielding intracellular accumulation or secretion of ribotoxins are described. Use of protease deficient strains and other methods of minimising breakdown of ribotoxin by protease are preferred.  Vectors and host strains for use in the methods are described.

Abstract: A roll which has a metallic core and an elastomeric envelope is obtained by assembling the envelope from a stack of discs each of which surrounds the core.  In order to impart to the envelope a desired elasticity, the discs contain a fibrous material and a plastic substance and are pressed against each other in the longitudinal direction of the core.  The plastic substance is hardenable within an interval exceeding 48 hours.  The pressing step is started with a delay following the step of placing the discs around the core such that the hardening begins prior to compressing and is terminated within an interval not less than 48 hours following the start of the pressing step.

Inventor: DOWNEY STEPHEN W
IPC: G01N15/10
Filed: 1993-07-23
Abstract: Disclosed is an apparatus which can serve to detect, count, size discriminate and analyze the chemical composition of particles in the air or process gases. In a preferred embodiment, the particles enter via a capillary (4 or 5) into a differentially pumped chamber (6). A pulsed laser (10) which is continuously fired is focused at an opening in the chamber. When the particles come into the path of the laser beam, the particles are fragmented and ionized. A dual time of flight massspectrum is produced, recorded with an oscilloscope (16) and analyzed with a computer (22). The mass spectrum information enables the determination of the chemical nature and concentration of the species of the particles, the particle size and the elemental composition of airborne particles in real time. Once these parameters are determined the source of the particles can be determined and eliminated from the environment and process. Thus, the inventive apparatus is advantageouslyused in conjunction with a facility i.e., a semiconductor manufacturing facility, that requires ultra-clean conditions.
